I can not buy half a year after the brake wheeled rear wheel (after a round of rotation once, I think), many times to the maintenance station to check the maintenance and replacement of the rear three bearings, the problem is temporarily resolved. Three days after the emergence of the above situation, once again to the maintenance station maintenance, after debugging, the situation some improved (Pine brake, but not brake car, after several debugging without cure). The staff said that there may be the locomotive rear wheel drum is not round to the (why did not the initial ring?), The problem is not resolved. I feel my car rear wheel is this: the brake tightened, and can be in the 30 yards a meter brake car, rear wheel, but do not go when the empty push do not go, the rear does not turn, like in the brakes. Brakes loose, in addition to 4 meters brake car, the other situation is tight and tight situation is the opposite, I do not know what is the reason? Please brothers urged, I would like to thank you!
Please answer downstairs, the current issue of this I still did not drop!
Is the kind of special sharp thing, the brake drum down to boring about, replace the brake shoes OK
Replacement of the brake pads on the ok!
Do you have a brake shoe? Loose the brake without the brake shoes, of course, not brake car, tighten the brake block is the iron did not brake the skin, and brake brakes friction and sometimes ringing, iron and iron can not ring it?
